Which of the following is an advantage of water tube boilers?

Water tube boilers have several distinct advantages, and one of the primary benefits is their ability to operate with high capacity and pressure. In water tube boilers, water flows through tubes that are heated externally by the combustion gases. This design allows them to withstand higher pressures, making them suitable for power generation and industrial applications where high steam output is essential.

Additionally, the water tube configuration contributes to efficient heat transfer and quick steam generation, which are critical for processes requiring rapid changes in steam demand. The design also minimizes the risk of water accumulation in the boiler, further enhancing safety and operational efficiency.

While compact size, the ability to use less water, and safety from explosions are generally advantages associated with certain types of boilers, the unique strength and operational capabilities of water tube boilers make their capacity to handle high pressure and steam output a key strength. This characteristic is particularly important for industries that demand reliability and efficiency in steam production under significant stresses.
